17、3 IEC:2009 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND SIMILAR PRODUCTS FOR SUPPLY VOLTAGES UP TO 1 100 V Part 2-13: Particular requirements and tests for auto transformers and power supply units incorporating auto transformers FOREWORD 1) The

18、 International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and

19、 electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical com

20、mittees; any IEC National Committee interested in the subject dealt with may Participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also Participate in this preparation. IEC collaborates closely with the International Organization f

21、or Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committe

22、e has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is ac

23、curate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regi

24、onal publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformi

25、ty with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any p

26、ersonal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative

27、references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible

28、 for identifying any or all such patent rights. International standard IEC 61558-2-13 has been prepared by IEC technical committee 96: Transformers, reactors, power supply units and similar products for low voltages up to 1 100 V. This second edition cancels and replaces the first edition published

29、in 1999. It constitutes a technical revision. The main changes consist of updating this part in accordance with Part 1 (2005), and increasing the supply voltages up to 1 100 V to be in line with the standards of TC 14. This part has the status of a group safety publication in accordance with IEC Gui

30、de 104: (1997): The preparation of safety publications and the use of basic safety publications and group safety publications. SANS 61558-2-13:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .61558-2-13 IEC:2009 5 The text of this standard

31、 is based on the following documents: FDIS Report on voting 96/318/FDIS 96/323/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

32、This part is intended to be used in conjunction with the latest edition of IEC 61558-1 and its amendments. It is based on the second edition (2005) of that standard. This part supplements or modifies the corresponding clauses in IEC 61558-1, so as to convert that publication into the IEC standard: P

33、articular requirements and tests for auto transformers and power supply units incorporating auto transformers. A list of all parts of the IEC 61558 series can be found on the IEC website under the title: Safety of transformers, reactors, power supply units and similar products for supply voltages up

34、 to 1 100 V. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the time of the next edition. Where a particular subclause of Part 1 is not mentioned in this part, that subclause applies as far as is reasona

35、ble. Where this part states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. In this part, the following print types are used: requirements proper: in roman type; test specifications: in italic type; explanatory matter: in smaller roman type: In

36、the text of this part, the words in bold are defined in Clause 3. Subclauses, notes, figures and tables additional to those in Part 1 are numbered starting from 101; supplementary annexes are entitled AA, BB, etc. The committee has decided that the contents of this publication will remain unchanged

37、until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. NOTE The attention of National Committees is drawn t

38、o the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the

39、 recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication.

41、h the safety of auto transformers for general applications and power supply units incorporating auto transformers for general applications. Transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless othe

42、rwise specified, from here onward, the term transformer covers auto transformers for general applications and power supply units incorporating auto transformers for general applications. NOTE 2 : For power supply units (linear) this part is applicable. For switch mode power supply units, IEC 61558-2

43、-16 is applicable together with this part. This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) independent or associated dry- type transformers. The windings may be encapsulated or non-encapsulated. The rated supply voltage does not exceed 1 1

44、00 V a.c., and the rated supply frequency and the internal operating frequencies do not exceed 500 Hz. The core power does not exceed: 2 kVA for single-phase transformers; 10 kVA for polyphase transformers. The rated output does not exceed: 40 kVA for single-phase transformers; 200 kVA for polyphase

45、 transformers. This part is applicable to transformers without limitation of the core power and the rated output both being subject to an agreement between the purchaser and the manufacturer. Where applicable, the no-load output voltage or the rated output voltage does not exceed 1 000 V a.c. or 1 4

46、15 V ripple-free d.c., and for independent transformers, the no-load output voltage and the rated output voltage exceeds 50 V a.c., or 120 V ripple-free d.c. This part is not applicable to external circuits and their components intended to be connected to the input terminals and output terminals of
